Today, with the rapid development of the cable industry, aluminum core cables are also making continuous progress, and aluminum core cables can also be seen in some very special projects. , the aluminum core cable is better than you think.
From the perspective of electrical performance, when the cross-section of the aluminum-core cable is 1.5 times that of the copper-core cable, its electrical performance is the same as that of the copper-core cable, achieving the same current-carrying capacity, resistance, and pressure loss. In addition, the advanced aluminum core cable insulation technology can also reduce the cross-sectional area of the aluminum core cable. For example, the advanced German compression technology can make the cross section of the aluminum core cable only need to increase within 11% on the basis of the copper core cable. Electrical performance, so laying the aluminum core cable can completely use the original copper core cable to lay the pipeline.
Secondly, from the perspective of the mechanical properties of the aluminum core cable, the extension performance, flexibility or bending performance of the aluminum core cable are very good. In addition, the aluminum core cable has excellent rebound performance, which makes the aluminum alloy cable stable during connection. Better performance. The advantages of aluminum core cables can be seen from the service life of aluminum core cables. The aluminum alloy cable is more chemically stable, and its surface can be rapidly oxidized at the moment of contact with the air to protect the aluminum alloy cable. Therefore, the corrosion resistance of aluminum alloy cables greatly improves the service life of aluminum alloy cables. The fourth is to see the advantages of aluminum alloy cables from the economic performance of aluminum alloy cables. Compared with copper core cables, aluminum alloy cables have lower cost and less investment. The purchase cost is low and the installation cost is also low.
Next is the safety performance of aluminum alloy cables. Historical practice has proved that aluminum alloy cables are absolutely safe in installation and use. Since the research and development of aluminum alloy cables, there has never been a fault, which is due to the excellent creep resistance and flame retardancy of aluminum alloy cables.
